Clark's Christmas Tree Farm is truly a family business. Bill Clark Sr. along with his oldest children started planting the farm in Cochrnaville, PA in 1998 while their first farm in West Chester was being developed and the children were still in high school. Today, all four of his children continue to help run the family business. Growing Christmas trees is a year-round enterprise; even in January you will see preparations of the ground and the removal the stumps for spring planting. Clark's Tree Farm has 35 acres planted in Douglas Fir Christmas trees.
